@dagar Is this related to the open detection PR?

[Ahrovan]

@LorenzMeier Probably a mistake occurred in your reply :)

[LorenzMeier]

No it's not.

[Ahrovan]

@dagar @LorenzMeier What is your opinion about this problem? Do you need more information for troubleshooting? I try with another pixhawk and send log file today (and I'll check #8475)

[dagar]

@Ahrovan it's possible your issue is related to #8703, #8643. I've discussed with @davids5 and have a potential fix to implement and test later tonight.

Could you expand on exactly what you did? When did you calibrate relative to flashing? How are you powering the pixhawk? Did you command a restart from QGroundControl (including selecting an airframe) or the reboot command in nuttx?

[dagar]

Could you try #9074?

[Ahrovan]

@dagar The problem persists with the latest version (v1.8.2 Stable Release)

@hansbonini and @Ahrovan could you answer to this:

And can you try latest master?

[julianoes]

Closing because no one followed up.

[Ahrovan]

I'm a follower. But there is no feedback from developers

@Ahrovan This request was waiting on a response here from you or @hansbonini:
#8927 (comment)

If you're happy to act as the stakeholder on the reporter side (?) I'm sure @julianoes is more than happy to reopen and continue investigation
